Shipping Dunnage

Protecting Cargo Through Multi-Modal Transport

Freight damage claims eat into margins and erode customer relationships. A carton arrives at its destination crushed, dented, or bearing evidence of movement during transit. An expensive component shifts inside its packaging and arrives inoperable. A pallet of finished goods loses product value because moisture penetrated during sea or road transport. In almost every case, the root cause traces back to inadequate or mismatched shipping dunnagethe protective materials that should have stabilised the load and absorbed shock.

At Ferrier Industrial, we work with manufacturers, exporters, and logistics operators who’ve learned that shipping dunnage isn’t an afterthought or a cost to minimise. It’s a critical investment in cargo integrity and supply chain reputation. The right dunnage material, matched to your cargo type and transport mode, can mean the difference between arriving flawless and arriving damaged. Whether you’re moving coils across intermodal networks, exporting fragile goods by container, or consolidating mixed freight for domestic road transport, selecting appropriate shipping dunnage requires understanding both material properties and real-world transport conditions.

Background: Freight Damage, Dunnage Requirements, and Selection Criteria

Cargo damage during transit stems from several mechanical realities. Vibration causes loose items to shift and rub against each other or container walls. Shockfrom forklift impact, sudden braking, rough loadingtransmits through packaging and can deform or break products. Moisture infiltration degrades paper-based packaging and corrodes metal goods. Temperature cycling in international containers can cause condensation and corrosion.

Shipping dunnage addresses these challenges by creating a stable, protective environment within the transport unit. It fills voids so items don’t shift. It absorbs vibration and impact energy. It provides a moisture barrier or ventilation pathway depending on product needs. It protects edges and corners from external damage (handling marks, forklift punctures, weather exposure).

The evaluation framework for shipping dunnage differs from static warehouse applications. You’re not just concerned with raw strength; you’re concerned with weight efficiency (extra dunnage adds freight cost), moisture behaviour (will it swell, rot, or promote condensation?), compatibility with different cargo types, reusability (can it be recovered and re-used or must it be discarded?), and regulatory compliance (export regulations often specify treatment or material restrictions).

For exporters, additional constraints apply. Fumigated pallets and dunnage meet specific phytosanitary requirements; documentation must accompany shipments. Cross-border movement may require ISPM-15 (International Standards for Phytosanitary Measures) heat-treatment or chemical certification. Some markets restrict certain timber species or require evidence of sustainable sourcing. Understanding those requirementsand ensuring your dunnage supplier can meet themis non-negotiable for international shipments.

Our Shipping Dunnage Portfolio and Material Options

We at Ferrier Industrial offer a structured range of shipping dunnage solutions, each designed for specific transport scenarios, cargo types, and durability or recyclability requirements.

LVL High-Friction Dunnage is our foundation offering for general freight protection. Engineered from laminated veneer lumber (eucalyptus-sourced, certified renewable), it provides consistent geometry and structural properties across every piece. The multi-use capability means a single dunnage block can stabilise multiple shipments before reaching end-of-life. We supply LVL in various cross-sections and lengths to accommodate different void-filling needs and cargo interfaces. The material is moisture-resistant (BWRboiling-water-resistantgrade available), reducing swelling or rot risk in humid transport or storage environments.

Hardwood Dunnage Blocks serve applications where maximum durability and load concentration matter. Seasoned hardwood can support sustained point loads without compression or splintering, ideal for coil transport, heavy machinery, or stacked freight where dunnage bears substantial weight. Hardwood dunnage is typically single-use (particularly for export applications subject to fumigation), but its strength-to-weight ratio justifies the material cost in high-value or critical-load scenarios.

Coil Dunnage and Specialist Blocking addresses the unique needs of metal coil, pipe, and tubular freight. Coils require radial support that prevents flattening or edge-contact damage. We supply bore-support blocks (shaped to nestle inside coil centres) and edge-protection solutions (wrapping or cradling coils to prevent external damage and corrosion). For intermodal coil transportwhere coils may transit truck, rail, and shipour dunnage systems are designed to stay in place through mode transitions and multiple handling cycles.

Industrial Dunnage Airbags provide void-filling and cushioning for road transport, particularly when freight consolidation means a truck bed isn’t fully utilised. Airbags are lightweight, reusable (within their rated cycle life), and can be deployed quickly. They work well for mixed cargo or situations where traditional blocking isn’t practical. We supply bags in various sizes and with compatible inflation and valve systems.

Custom Shipping Dunnage Solutions acknowledge that not every shipment fits a standard template. We can fabricate bespoke blocking, edge protection, or support structures from timber, steel, or composite materials. If your cargo has unique geometry, requires specific interface dimensions, or needs to meet particular regulatory or customer specifications, we can design and build it.

• LVL dunnage blocks in multiple cross-sections for general freight stabilisation, void-filling, and moisture-resistant applications
• Hardwood dunnage for high-load-bearing scenarios, export shipments, and applications requiring superior durability and compression resistance
• Specialist coil dunnage including bore supports, edge protectors, and intermodal-rated blocking for metal freight and tubular cargo
• Industrial dunnage airbags for truck consolidation, mixed cargo, and flexible void-filling where traditional blocking space is limited
• Custom fabricated solutions for unique cargo geometries, regulatory requirements, or customer-specific interface specifications

Shipping Dunnage Material Selection: Matching Solutions to Cargo and Transport

Not all freight has the same dunnage requirements. Selecting the right material and configuration depends on cargo type, transport mode, distance, environmental exposure, and end-of-life handling.

Domestic Road Transport of mixed manufactured goods typically benefits from LVL dunnage or airbags. Freight is protected from weather (enclosed truck), but vibration and braking forces can cause movement. Lightweight dunnage that’s easy for drivers to position and remove reduces handling time and labour cost. Reusable solutions minimise disposal burden. If the freight destination will recycle or return dunnage, LVL blocks are straightforward to recover and repurpose.

Export Container Shipments demand higher specification dunnage. Ocean transit introduces salt spray, moisture cycling, and prolonged exposure to weather during loading/unloading. Fumigation or heat-treatment requirements apply to many timbers; documentation must accompany shipments. Hardwood dunnage, when treated and certified, meets these requirements. LVL (if sourced from certified sustainable forests and treated appropriately) also works, but regulatory compliance requires careful supplier verification. For long sea voyages, moisture resistance becomes critical; swollen or rotting dunnage loses its protective function and can contaminate other shipments or attract port authority scrutiny.

Coil and Metal Freight Transport requires specialist dunnage that prevents both internal deformation (the coil flattening under its own weight) and external corrosion (coil edges scoring or oxidising due to contact with steel or moisture). Bore-support dunnage, combined with protective wrapping or edge-guard systems, addresses both challenges. For intermodal coil shipmentswhere a coil might travel truck to railhead, remain on a rail car, then move to dockside and into a containerdunnage must withstand multiple handling transitions without loosening or migrating. Our coil dunnage systems are engineered with that scenario in mind.

Fragile or High-Value Goods (electronics, precision instruments, glassware, artwork) benefit from cushioned dunnage and impact-absorbing systems. Foam dunnage, protective wrapping, and carefully positioned blocking reduce shock transmission. In these cases, dunnage cost is often a small fraction of cargo value; the investment in premium protection is justified. We can design custom solutions using materials that combine strength (load-bearing) with compliance (shock absorption).

Food, Pharmaceutical, or Chemical Freight may have specific dunnage restrictions. Food-contact materials must be food-approved; chemical shipments may require dunnage that resists corrosion or degradation from chemical exposure. Pharmaceutical goods moving internationally may require documentation that dunnage hasn’t been treated with prohibited fumigants. Understanding regulatory or industry-specific requirements upfront prevents costly delays or rejections at destination.

Integration Across Transport Modes and Handling Workflows

Shipping dunnage must accommodate the entire journeynot just the initial packing, but every subsequent handling event. A coil dunnage system designed only for truck transport will fail if that same coil subsequently moves to rail or is consolidated into a container with other coils.

At Ferrier Industrial, we approach multi-modal transport by designing dunnage that remains stable through mode transitions. Coil support blocks are secured so they won’t shift if a coil is lifted by different equipment or rotated during consolidation. Edge protection is robust enough to withstand forklift contact, rail car jolts, and container stacking compression. If dunnage must be removed (e.g., before container unpacking), it’s configured so removal doesn’t destabilise the cargo.

Weight distribution also matters across modes. A truck can carry heavier dunnage per shipment because payload capacity is generous. A container, by contrast, has volume and weight constraints; excessive dunnage eats freight cost without proportional protection benefit. We help clients balance protection against transport economics, sometimes recommending lighter dunnage for long-distance container moves and heavier dunnage for domestic road transport where protection intensity matters more than weight efficiency.

Handling interfacesparticularly for automated systemsare increasingly important. If your destination uses automated container unloading equipment, dunnage can’t protrude in ways that jam machinery. If your freight moves through consolidation hubs where forklifts handle pallets at high speed, dunnage must be secured so it won’t fall or shift during that handling. These operational realities shape dunnage design as much as material properties do.

Regulatory Compliance, Documentation, and Export Considerations

For international shipments, regulatory compliance with shipping dunnage is non-negotiable. Many countries enforce ISPM-15 (Phytosanitary) standards, requiring that timber dunnage be either heat-treated to specified temperatures or chemically treated (typically methyl bromide) and accompanied by certification documentation.

Some exporters prefer to work with pre-certified dunnage suppliers who maintain ongoing compliance with these standards. Others source dunnage locally and manage certification in-house. Either way, documentationa phytosanitary certificate or equivalentmust travel with the shipment. Lack of proper documentation can result in port rejections, shipment delays, or forced destruction of dunnage and potential cargo damage.

Additionally, importing countries sometimes place restrictions on timber species (e.g., prohibiting certain endangered hardwoods) or requiring evidence of sustainable sourcing (e.g., FSC or PEFC certification). If your freight is moving to environmentally regulated markets, understanding those restrictions upfront prevents last-minute surprises.

At Ferrier Industrial, we maintain supplier relationships and documentation systems that keep us current with evolving phytosanitary and environmental regulations across key export destinations. When we discuss shipping dunnage for an export project, we confirm regulatory requirements and specify dunnage (material, treatment, certification) that will pass inspection at destination.

Sustainability and End-of-Life Recovery for Shipping Dunnage

A growing number of organisations are asking not just whether dunnage protects cargo, but what happens to it after the shipment arrives. Single-use dunnage destined for landfill carries both environmental and financial costs. Reusable solutions offer a better calculus if the supply chain and logistics support recovery.

LVL dunnage, by design, is multi-use. A single block can stabilise multiple shipments over months or years before damage or wear necessitates disposal. When end-of-life arrives, LVL is recyclable (chipped for energy recovery or down-cycled into composite products) rather than destined for landfill.

For export shipments, reusability is more complicated. Once dunnage leaves your operation, recovery logistics become expensive or impractical. In those cases, selecting durable, responsibly sourced materialrather than cheap, disposable optionsstill offers an environmental benefit. Hardwood dunnage from certified sustainable forests, or LVL from renewable sources, represents a smaller environmental footprint than indiscriminate timber harvesting, even if the dunnage itself isn’t recovered.

We counsel clients on this balance pragmatically. If your freight is returning via reverse logistics and dunnage can be recovered, design for multi-use and establish recovery protocols. If dunnage is leaving the system, prioritise durability and material responsibility; the longer each piece remains in service before disposal, the lower its effective environmental impact.

Key Procurement Considerations for Shipping Dunnage

When evaluating shipping dunnage options, several decision criteria should shape your selection:

• Cargo protection requirements: assess shock sensitivity, vibration tolerance, moisture risk, and temperature cycling exposure to specify the right material properties and cushioning approach
• Transport mode and distance: confirm whether dunnage must remain stable through intermodal transitions, consolidation hubs, or extended sea transit; prioritise moisture resistance for long-distance or international moves
• Regulatory and compliance obligations: verify phytosanitary requirements, species restrictions, and sustainability certifications required by destination markets; confirm supplier documentation capability
• Reusability and recovery logistics: determine whether dunnage will be recovered after shipment or is effectively single-use; if reusable, establish recovery protocols and cleaning/inspection standards
• Weight efficiency and freight cost impact: evaluate whether premium dunnage justified by protection value is offset by added freight cost; aim for a balance that minimises total cost-in-use including damage claims
• Handling compatibility: confirm dunnage won’t interfere with standard handling equipment (forklifts, automated systems, port machinery) and that removal or transition won’t destabilise cargo
• Supplier reliability and documentation: assess whether your dunnage supplier can maintain consistent quality, provide required certifications, and support rapid response if a shipment encounters unexpected challenges

How We Support Shipping Dunnage Supply and Optimisation

When an organisation approaches Ferrier Industrial with a shipping dunnage requirement, we begin by understanding the complete transport scenario. We ask about cargo type and value, typical transport distance and mode (domestic road, export container, intermodal rail), environmental exposure during transit, destination regulations, and whether dunnage is expected to be recovered or is single-use.

From that information, we recommend a dunnage specificationmaterial type, block sizes, configuration, and any protection or handling features that align with your scenario. We can provide samples for testing, arrange drawings or dimensional verification, and discuss any custom fabrication if standard solutions don’t fit your geometry.

We’re also experienced in the regulatory nuances that catch many organisations off-guard. If your freight is moving internationally, we confirm phytosanitary compliance, source material with appropriate certifications, and arrange documentation. If your destination has specific material restrictions or sustainability requirements, we account for those in specification. That diligence reduces risk of port delays or rejections.

Once a dunnage specification is agreed, we manage supply with the same reliability we apply to other product families. If you need consistent orders (e.g., weekly shipments of coil dunnage) or variable demand (seasonal exports), we scale supply accordingly. If a shipment encounters unexpected damage and you need rapid root-cause analysis and solution development, our team investigates and troubleshoots in real time.

Our ANZ operationsheadquartered in Auckland and Unanderramean we can support both Australian and New Zealand exporters, as well as organisations managing cross-border freight. We understand local regulatory nuances, carrier requirements, and the particular challenges of moving goods in our region.

Practical Steps: Specifying and Sourcing Shipping Dunnage

If you’re currently managing freight damage or know your dunnage selection could be more deliberate, a structured approach ensures you land on the right solution.

• Audit recent shipments: review damage claims, inspect dunnage that arrived with damaged freight, and identify patterns (moisture intrusion, shock damage, cargo shift, corrosion) to pinpoint dunnage gaps
• Document your transport scenarios: map typical cargo types, routes, transport modes, and environmental exposure for each; note any international shipments and associated regulatory requirements
• Assess regulatory requirements: confirm phytosanitary standards, species restrictions, and sustainability certifications required by your destination markets; contact your shipping agents or destination ports if uncertain
• Request technical specifications and samples: work with a dunnage supplier to trial material options in your packing process; evaluate ease of positioning, removal, and recovery (if applicable)
• Conduct a pilot shipment: use recommended dunnage for a small number of shipments and track arrival condition, handling feedback, and any damage; adjust specifications based on real-world performance
• Establish a long-term supply agreement: once a dunnage solution is validated, agree with your supplier on pricing, delivery schedules, documentation provision, and support for any regulatory or operational changes
